Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, brake cleaner, torque wrench, multimeter, and safety glasses.
Ensure the vehicle is parked on a flat surface and the engine is cool before starting.

2. Inspect and Address Fluid Leaks

Check for oil or coolant leaks:
- Visually inspect the engine and surrounding components.
- Clean any spilled fluids and identify their source.
If oil is leaking, replace the oil filter and gaskets as necessary.

3. Brake Inspection and Replacement

Remove the wheel to access the brake components:
- Use a jack and jack stands for safety.
Inspect brake pads and rotors:
- If pads are worn down to the metal, replace them.
- If rotors are scored, consider resurfacing or replacing them.
Reassemble the brake components and torque to manufacturer's specifications.

4. Electrical Inspection

Check wiring and connectors for damage:
- Inspect for frayed wires or burnt connectors.
- Replace any damaged wiring or connectors.
Use a multimeter to check for shorts in electrical systems.
